Identify the pros and cons of jade

<

We all know that jadeite is divided into A, B, C and B+C goods. Before identifying the pros and cons of jade, you must know the definition of these four jadeites.

Jadeite A refers to natural jadeite that has not been filled and added, dyed and treated; although the main component of jadeite B is still natural jadeite, the color will be more natural, but after filling, the glue will age after aging. It affects the transparency and gloss of jade, the bright and vivid color of the color, etc.; the jadeite C is the jade that has been dyed; the jadeite B+C is naturally the jade which is filled and dyed at the same time. In the professional jade identification center, there are many professional instruments that can effectively identify jade. For example, in the infrared spectrum band, in the range of 2800~3000, the curve of A goods is smoothly rising; the curve of B goods is exactly the opposite, which is frequently floating up and down and disorderly.
